Fixed bug #166
From the autoconf obsolete macros documentation:
Macro: AC_CANONICAL_SYSTEM
Determine the system type and set output variables to the names of the canonical system types. See section Getting the Canonical System Type, for details about the variables this macro sets.
The user is encouraged to use either AC_CANONICAL_BUILD, or AC_CANONICAL_HOST, or AC_CANONICAL_TARGET, depending on the needs. Using AC_CANONICAL_TARGET is enough to run the two other macros.
From the documentation for the canonical environments:
case $target in
i386-*-mach* | i386-*-gnu*)
obj_format=aout emulation=mach bfd_gas=yes ;;
i960-*-bout) obj_format=bout ;;
esac
Note that the above example uses $target because it's taken from a tool which can be built on some architecture ($build), run on another ($host), but yet handle data for a third architecture ($target). Such tools are usually part of a compiler suite, they generate code for a specific $target.
However $target should be meaningless for most packages. If you want to base a decision on the system where your program will be run, make sure you use the $host variable.

| 0 | 34 1.2.0: |
| 35 Added SDL_VIDEOEXPOSE event to signal that the screen needs to | |
| 36 be redrawn. This is currently only delivered to OpenGL windows | |
| 37 on X11, though it may be delivered in the future when the video | |
| 38 memory is lost under DirectX. | |
| 39 | |
| 40 1.1.8: | |
| 41 You can pass SDL_NOFRAME to SDL_VideoMode() to create a window | |
| 42 that has no title bar or frame decoration. Fullscreen video | |
| 43 modes automatically have this flag set. | |
| 44 | |
| 45 Added a function to query the clipping rectangle for a surface: | |
| 46 void SDL_GetClipRect(SDL_Surface *surface, SDL_Rect *rect) | |
| 47 | |
| 48 Added a function to query the current event filter: | |
| 49 SDL_EventFilter SDL_GetEventFilter(void) | |
| 50 | |
| 51 If you pass -1 to SDL_ShowCursor(), it won't change the current | |
| 52 cursor visibility state, but will still return it. | |
| 53 | |
| 54 SDL_LockSurface() and SDL_UnlockSurface() are recursive, meaning | |
| 55 you can nest them as deep as you want, as long as each lock call | |
| 56 has a matching unlock call. The surface remains locked until the | |
| 57 last matching unlock call. | |
| 58 | |
| 59 Note that you may not blit to or from a locked surface. | |
| 60 | |
| 61 1.1.7: | |
| 62 The SDL_SetGammaRamp() and SDL_GetGammaRamp() functions now take | |
| 63 arrays of Uint16 values instead of Uint8 values. For the most part, | |
| 64 you can just take your old values and shift them up 8 bits to get | |
| 65 new correct values for your gamma ramps. | |
| 66 | |
| 67 You can pass SDL_RLEACCEL in flags passed to SDL_ConvertSurface() | |
| 68 and SDL will try to RLE accelerate colorkey and alpha blits in the | |
| 69 resulting surface. | |
| 70 | |
| 71 1.1.6: | |
| 72 Added a function to return the thread ID of a specific thread: | |
| 73 Uint32 SDL_GetThreadID(SDL_Thread *thread) | |
| 74 If 'thread' is NULL, this function returns the id for this thread. | |
| 75 | |
| 76 1.1.5: | |
| 77 The YUV overlay structure has been changed to use an array of | |
| 78 pitches and pixels representing the planes of a YUV image, to | |
| 79 better enable hardware acceleration. The YV12 and IYUV formats | |
| 80 each have three planes, corresponding to the Y, U, and V portions | |
| 81 of the image, while packed pixel YUV formats just have one plane. | |
| 82 | |
| 83 For palettized mode (8bpp), the screen colormap is now split in | |
| 84 a physical and a logical palette. The physical palette determines | |
| 85 what colours the screen pixels will get when displayed, and the | |
| 86 logical palette controls the mapping from blits to/from the screen. | |
| 87 A new function, SDL_SetPalette() has been added to change | |
| 88 logical and physical palettes separately. SDL_SetColors() works | |
| 89 just as before, and is equivalent to calling SDL_SetPalette() with | |
| 90 a flag argument of (SDL_LOGPAL|SDL_PHYSPAL). | |
| 91 | |
| 92 SDL_BlitSurface() no longer modifies the source rectangle, only the | |
| 93 destination rectangle. The width/height members of the destination | |
| 94 rectangle are ignored, only the position is used. | |
| 95 | |
| 96 The old source clipping function SDL_SetClipping() has been replaced | |
| 97 with a more useful function to set the destination clipping rectangle: | |
| 98 SDL_bool SDL_SetClipRect(SDL_Surface *surface, SDL_Rect *rect) | |
| 99 | |
| 100 Added a function to see what subsystems have been initialized: | |
| 101 Uint32 SDL_WasInit(Uint32 flags) | |
| 102 | |
| 103 The Big Alpha Flip: SDL now treats alpha as opacity like everybody | |
| 104 else, and not as transparency: | |
| 105 | |
| 106 A new cpp symbol: SDL_ALPHA_OPAQUE is defined as 255 | |
| 107 A new cpp symbol: SDL_ALPHA_TRANSPARENT is defined as 0 | |
| 108 Values between 0 and 255 vary from fully transparent to fully opaque. | |
| 109 | |
| 110 New functions: | |
| 111 SDL_DisplayFormatAlpha() | |
| 112 Returns a surface converted to a format with alpha-channel | |
| 113 that can be blit efficiently to the screen. (In other words, | |
| 114 like SDL_DisplayFormat() but the resulting surface has | |
| 115 an alpha channel.) This is useful for surfaces with alpha. | |
| 116 SDL_MapRGBA() | |
| 117 Works as SDL_MapRGB() but takes an additional alpha parameter. | |
| 118 SDL_GetRGBA() | |
| 119 Works as SDL_GetRGB() but also returns the alpha value | |
| 120 (SDL_ALPHA_OPAQUE for formats without an alpha channel) | |
| 121 | |
| 122 Both SDL_GetRGB() and SDL_GetRGBA() now always return values in | |
| 123 the [0..255] interval. Previously, SDL_GetRGB() would return | |
| 124 (0xf8, 0xfc, 0xf8) for a completely white pixel in RGB565 format. | |
| 125 (N.B.: This is broken for bit fields < 3 bits.) | |
| 126 | |
| 127 SDL_MapRGB() returns pixels in which the alpha channel is set opaque. | |
| 128 | |
| 129 SDL_SetAlpha() can now be used for both setting the per-surface | |
| 130 alpha, using the new way of thinking of alpha, and also to enable | |
| 131 and disable per-pixel alpha blending for surfaces with an alpha | |
| 132 channel: | |
| 133 To disable alpha blending: | |
| 134 SDL_SetAlpha(surface, 0, 0); | |
| 135 To re-enable alpha blending: | |
| 136 SDL_SetAlpha(surface, SDL_SRCALPHA, 0); | |
| 137 Surfaces with an alpha channel have blending enabled by default. | |
| 138 | |
| 139 SDL_SetAlpha() now accepts SDL_RLEACCEL as a flag, which requests | |
| 140 RLE acceleration of blits, just as like with SDL_SetColorKey(). | |
| 141 This flag can be set for both surfaces with an alpha channel | |
| 142 and surfaces with an alpha value set by SDL_SetAlpha(). | |
| 143 As always, RLE surfaces must be locked before pixel access is | |
| 144 allowed, and unlocked before any other SDL operations are done | |
| 145 on it. | |
| 146 | |
| 147 The blit semantics for surfaces with and without alpha and colorkey | |
| 148 have now been defined: | |
| 149 | |
| 150 RGBA->RGB: | |
| 151 SDL_SRCALPHA set: | |
| 152 alpha-blend (using alpha-channel). | |
| 153 SDL_SRCCOLORKEY ignored. | |
| 154 SDL_SRCALPHA not set: | |
| 155 copy RGB. | |
| 156 if SDL_SRCCOLORKEY set, only copy the pixels matching the | |
| 157 RGB values of the source colour key, ignoring alpha in the | |
| 158 comparison. | |
| 159 | |
| 160 RGB->RGBA: | |
| 161 SDL_SRCALPHA set: | |
| 162 alpha-blend (using the source per-surface alpha value); | |
| 163 set destination alpha to opaque. | |
| 164 SDL_SRCALPHA not set: | |
| 165 copy RGB, set destination alpha to opaque. | |
| 166 both: | |
| 167 if SDL_SRCCOLORKEY set, only copy the pixels matching the | |
| 168 source colour key. | |
| 169 | |
| 170 RGBA->RGBA: | |
| 171 SDL_SRCALPHA set: | |
| 172 alpha-blend (using the source alpha channel) the RGB values; | |
| 173 leave destination alpha untouched. [Note: is this correct?] | |
| 174 SDL_SRCCOLORKEY ignored. | |
| 175 SDL_SRCALPHA not set: | |
| 176 copy all of RGBA to the destination. | |
| 177 if SDL_SRCCOLORKEY set, only copy the pixels matching the | |
| 178 RGB values of the source colour key, ignoring alpha in the | |
| 179 comparison. | |
| 180 | |
| 181 RGB->RGB: | |
| 182 SDL_SRCALPHA set: | |
| 183 alpha-blend (using the source per-surface alpha value). | |
| 184 SDL_SRCALPHA not set: | |
| 185 copy RGB. | |
| 186 both: | |
| 187 if SDL_SRCCOLORKEY set, only copy the pixels matching the | |
| 188 source colour key. | |
| 189 | |
| 190 As a special case, blits from surfaces with per-surface alpha | |
| 191 value of 128 (50% transparency) are optimised and much faster | |
| 192 than other alpha values. This does not apply to surfaces with | |
| 193 alpha channels (per-pixel alpha). | |
| 194 | |
| 195 New functions for manipulating the gamma of the display have | |
| 196 been added: | |
| 197 int SDL_SetGamma(float red, float green, float blue); | |
| 198 int SDL_SetGammaRamp(Uint8 *red, Uint8 *green, Uint8 *blue); | |
| 199 int SDL_GetGammaRamp(Uint8 *red, Uint8 *green, Uint8 *blue); | |
| 200 Gamma ramps are tables with 256 entries which map the screen color | |
| 201 components into actually displayed colors. For an example of | |
| 202 implementing gamma correction and gamma fades, see test/testgamma.c | |
| 203 Gamma control is not supported on all hardware. | |
| 204 | |
| 205 1.1.4: | |
| 206 The size of the SDL_CDtrack structure changed from 8 to 12 bytes | |
| 207 as the size of the length member was extended to 32 bits. | |
| 208 | |
| 209 You can now use SDL for 2D blitting with a GL mode by passing the | |
| 210 SDL_OPENGLBLIT flag to SDL_SetVideoMode(). You can specify 16 or | |
| 211 32 bpp, and the data in the framebuffer is put into the GL scene | |
| 212 when you call SDL_UpdateRects(), and the scene will be visible | |
| 213 when you call SDL_GL_SwapBuffers(). | |
| 214 | |
| 215 Run the "testgl" test program with the -logo command line option | |
| 216 to see an example of this blending of 2D and 3D in SDL. | |
| 217 | |
| 218 1.1.3: | |
| 219 Added SDL_FreeRW() to the API, to complement SDL_AllocRW() | |
| 220 | |
| 221 Added resizable window support - just add SDL_RESIZABLE to the | |
| 222 SDL_SetVideoMode() flags, and then wait for SDL_VIDEORESIZE events. | |
| 223 See SDL_events.h for details on the new SDL_ResizeEvent structure. | |
| 224 | |
| 225 Added condition variable support, based on mutexes and semaphores. | |
| 226 SDL_CreateCond() | |
| 227 SDL_DestroyCond() | |
| 228 SDL_CondSignal() | |
| 229 SDL_CondBroadcast() | |
| 230 SDL_CondWait() | |
| 231 SDL_CondTimedWait() | |
| 232 The new function prototypes are in SDL_mutex.h | |
| 233 | |
| 234 Added counting semaphore support, based on the mutex primitive. | |
| 235 SDL_CreateSemaphore() | |
| 236 SDL_DestroySemaphore() | |
| 237 SDL_SemWait() | |
| 238 SDL_SemTryWait() | |
| 239 SDL_SemWaitTimeout() | |
| 240 SDL_SemPost() | |
| 241 SDL_SemValue() | |
| 242 The new function prototypes are in SDL_mutex.h | |
| 243 | |
| 244 Added support for asynchronous blitting. To take advantage of this, | |
| 245 you must set the SDL_ASYNCBLIT flag when setting the video mode and | |
| 246 creating surfaces that you want accelerated in this way. You must | |
| 247 lock surfaces that have this flag set, and the lock will block until | |
| 248 any queued blits have completed. | |
| 249 | |
| 250 Added YUV video overlay support. | |
| 251 The supported YUV formats are: YV12, IYUV, YUY2, UYVY, and YVYU. | |
| 252 This function creates an overlay surface: | |
| 253 SDL_CreateYUVOverlay() | |
| 254 You must lock and unlock the overlay to get access to the data: | |
| 255 SDL_LockYUVOverlay() SDL_UnlockYUVOverlay() | |
| 256 You can then display the overlay: | |
| 257 SDL_DisplayYUVOverlay() | |
| 258 You must free the overlay when you are done using it: | |
| 259 SDL_FreeYUVOverlay() | |
| 260 See SDL_video.h for the full function prototypes. | |
| 261 | |
| 262 The joystick hat position constants have been changed: | |
| 263 Old constant New constant | |
| 264 ------------ ------------ | |
| 265 0 SDL_HAT_CENTERED | |
| 266 1 SDL_HAT_UP | |
| 267 2 SDL_HAT_RIGHTUP | |
| 268 3 SDL_HAT_RIGHT | |
| 269 4 SDL_HAT_RIGHTDOWN | |
| 270 5 SDL_HAT_DOWN | |
| 271 6 SDL_HAT_LEFTDOWN | |
| 272 7 SDL_HAT_LEFT | |
| 273 8 SDL_HAT_LEFTUP | |
| 274 The new constants are bitmasks, so you can check for the | |
| 275 individual axes like this: | |
| 276 if ( hat_position & SDL_HAT_UP ) { | |
| 277 } | |
| 278 and you'll catch left-up, up, and right-up. | |
| 279 | |
| 280 1.1.2: | |
| 281 Added multiple timer support: | |
| 282 SDL_AddTimer() and SDL_RemoveTimer() | |
| 283 | |
| 284 SDL_WM_SetIcon() now respects the icon colorkey if mask is NULL. | |
| 285 | |
| 286 1.1.0: | |
| 287 Added initial OpenGL support. | |
| 288 First set GL attributes (such as RGB depth, alpha depth, etc.) | |
| 289 SDL_GL_SetAttribute() | |
| 290 Then call SDL_SetVideoMode() with the SDL_OPENGL flag. | |
| 291 Perform all of your normal GL drawing. | |
| 292 Finally swap the buffers with the new SDL function: | |
| 293 SDL_GL_SwapBuffers() | |
| 294 See the new 'testgl' test program for an example of using GL with SDL. | |
| 295 | |
| 296 You can load GL extension functions by using the function: | |
| 297 SDL_GL_LoadProcAddress() | |
| 298 | |
| 299 Added functions to initialize and cleanup specific SDL subsystems: | |
| 300 SDL_InitSubSystem() and SDL_QuitSubSystem() | |
| 301 | |
| 302 Added user-defined event type: | |
| 303 typedef struct { | |
| 304 Uint8 type; | |
| 305 int code; | |
| 306 void *data1; | |
| 307 void *data2; | |
| 308 } SDL_UserEvent; | |
| 309 This structure is in the "user" member of an SDL_Event. | |
| 310 | |
| 311 Added a function to push events into the event queue: | |
| 312 SDL_PushEvent() | |
| 313 | |
| 314 Example of using the new SDL user-defined events: | |
| 315 { | |
| 316 SDL_Event event; | |
| 317 | |
| 318 event.type = SDL_USEREVENT; | |
| 319 event.user.code = my_event_code; | |
| 320 event.user.data1 = significant_data; | |
| 321 event.user.data2 = 0; | |
| 322 SDL_PushEvent(&event); | |
| 323 } | |
| 324 | |
| 325 Added a function to get mouse deltas since last query: | |
| 326 SDL_GetRelativeMouseState() | |
| 327 | |
| 328 Added a boolean datatype to SDL_types.h: | |
| 329 SDL_bool = { SDL_TRUE, SDL_FALSE } | |
| 330 | |
| 331 Added a function to get the current audio status: | |
| 332 SDL_GetAudioState(); | |
| 333 It returns one of: | |
| 334 SDL_AUDIO_STOPPED, | |
| 335 SDL_AUDIO_PLAYING, | |
| 336 SDL_AUDIO_PAUSED | |
| 337 | |
| 338 Added an AAlib driver (ASCII Art) - by Stephane Peter. | |
| 339 | |
| 340 1.0.6: | |
| 341 The input grab state is reset after each call to SDL_SetVideoMode(). | |
| 342 The input is grabbed by default in fullscreen mode, and ungrabbed in | |
| 343 windowed mode. If you want to set input grab to a particular value, | |
| 344 you should set it after each call to SDL_SetVideoMode(). | |
| 345 | |
| 346 1.0.5: | |
| 347 Exposed SDL_AudioInit(), SDL_VideoInit() | |
| 348 Added SDL_AudioDriverName() and SDL_VideoDriverName() | |
| 349 | |
| 350 Added new window manager function: | |
| 351 SDL_WM_ToggleFullScreen() | |
| 352 This is currently implemented only on Linux | |
| 353 | |
| 354 The ALT-ENTER code has been removed - it's not appropriate for a | |
| 355 lib to bind keys when they aren't even emergency escape sequences. | |
| 356 | |
| 357 ALT-ENTER functionality can be implemented with the following code: | |
| 358 | |
| 359 int Handle_AltEnter(const SDL_Event *event) | |
| 360 { | |
| 361 if ( event->type == SDL_KEYDOWN ) { | |
| 362 if ( (event->key.keysym.sym == SDLK_RETURN) && | |
| 363 (event->key.keysym.mod & KMOD_ALT) ) { | |
| 364 SDL_WM_ToggleFullScreen(SDL_GetVideoSurface()); | |
| 365 return(0); | |
| 366 } | |
| 367 } | |
| 368 return(1); | |
| 369 } | |
| 370 SDL_SetEventFilter(Handle_AltEnter); | |
| 371 | |
| 372 1.0.3: | |
| 373 Under X11, if you grab the input and hide the mouse cursor, | |
| 374 the mouse will go into a "relative motion" mode where you | |
| 375 will always get relative motion events no matter how far in | |
| 376 each direction you move the mouse - relative motion is not | |
| 377 bounded by the edges of the window (though the absolute values | |
| 378 of the mouse positions are clamped by the size of the window). | |
| 379 The SVGAlib, framebuffer console, and DirectInput drivers all | |
| 380 have this behavior naturally, and the GDI and BWindow drivers | |
| 381 never go into "relative motion" mode. | |
| 382 | |
| 383 1.0.2: | |
| 384 Added a function to enable keyboard repeat: | |
| 385 SDL_EnableKeyRepeat() | |
| 386 | |
| 387 Added a function to grab the mouse and keyboard input | |
| 388 SDL_WM_GrabInput() | |
| 389 | |
| 390 Added a function to iconify the window. | |
| 391 SDL_WM_IconifyWindow() | |
| 392 If this function succeeds, the application will receive an event | |
| 393 signaling SDL_APPACTIVE event | |
| 394 | |
| 395 1.0.1: | |
| 396 Added constants to SDL_audio.h for 16-bit native byte ordering: | |
| 397 AUDIO_U16SYS, AUDIO_S16SYS | |
| 398 | |
| 399 1.0.0: | |
| 400 New public release | |
| 401 | |
| 402 Version 0.11: | |
| 403 | |
| 404 0.11.5: | |
| 405 A new function SDL_GetVideoSurface() has been added, and returns | |
| 406 a pointer to the current display surface. | |
| 407 | |
| 408 SDL_AllocSurface() has been renamed SDL_CreateRGBSurface(), and | |
| 409 a new function SDL_CreateRGBSurfaceFrom() has been added to allow | |
| 410 creating an SDL surface from an existing pixel data buffer. | |
| 411 | |
| 412 Added SDL_GetRGB() to the headers and documentation. | |
| 413 | |
| 414 0.11.4: | |
| 415 SDL_SetLibraryPath() is no longer meaningful, and has been removed. | |
| 416 | |
| 417 0.11.3: | |
| 418 A new flag for SDL_Init(), SDL_INIT_NOPARACHUTE, prevents SDL from | |
| 419 installing fatal signal handlers on operating systems that support | |
| 420 them. | |
| 421 | |
| 422 Version 0.9: | |
| 423 | |
| 424 0.9.15: | |
| 425 SDL_CreateColorCursor() has been removed. Color cursors should | |
| 426 be implemented as sprites, blitted by the application when the | |
| 427 cursor moves. To get smooth color cursor updates when the app | |
| 428 is busy, pass the SDL_INIT_EVENTTHREAD flag to SDL_Init(). This | |
| 429 allows you to handle the mouse motion in another thread from an | |
| 430 event filter function, but is currently only supported by Linux | |
| 431 and BeOS. Note that you'll have to protect the display surface | |
| 432 from multi-threaded access by using mutexes if you do this. | |
| 433 | |
| 434 Thread-safe surface support has been removed from SDL. | |
| 435 This makes blitting somewhat faster, by removing SDL_MiddleBlit(). | |
| 436 Code that used SDL_MiddleBlit() should use SDL_LowerBlit() instead. | |
| 437 You can make your surfaces thread-safe by allocating your own | |
| 438 mutex and making lock/unlock calls around accesses to your surface. | |
| 439 | |
| 440 0.9.14: | |
| 441 SDL_GetMouseState() now takes pointers to int rather than Uint16. | |
| 442 | |
| 443 If you set the SDL_WINDOWID environment variable under UNIX X11, | |
| 444 SDL will use that as the main window instead of creating it's own. | |
| 445 This is an unsupported extension to SDL, and not portable at all. | |
| 446 | |
| 447 0.9.13: | |
| 448 Added a function SDL_SetLibraryPath() which can be used to specify | |
| 449 the directory containing the SDL dynamic libraries. This is useful | |
| 450 for commercial applications which ship with particular versions | |
| 451 of the libraries, and for security on multi-user systems. | |
| 452 If this function is not used, the default system directories are | |
| 453 searched using the native dynamic object loading mechanism. | |
| 454 | |
| 455 In order to support C linkage under Visual C++, you must declare | |
| 456 main() without any return type: | |
| 457 main(int argc, char *argv[]) { | |
| 458 /* Do the program... */ | |
| 459 return(0); | |
| 460 } | |
| 461 C++ programs should also return a value if compiled under VC++. | |
| 462 | |
| 463 The blit_endian member of the SDL_VideoInfo struct has been removed. | |
| 464 | |
| 465 SDL_SymToASCII() has been replaced with SDL_GetKeyName(), so there | |
| 466 is now no longer any function to translate a keysym to a character. | |
| 467 | |
| 468 The SDL_keysym structure has been extended with a 'scancode' and | |
| 469 'unicode' member. The 'scancode' is a hardware specific scancode | |
| 470 for the key that was pressed, and may be 0. The 'unicode' member | |
| 471 is a 16-bit UNICODE translation of the key that was pressed along | |
| 472 with any modifiers or compose keys that have been pressed. | |
| 473 If no UNICODE translation exists for the key, 'unicode' will be 0. | |
| 474 | |
| 475 Added a function SDL_EnableUNICODE() to enable/disable UNICODE | |
| 476 translation of character keypresses. Translation defaults off. | |
| 477 | |
| 478 To convert existing code to use the new API, change code which | |
| 479 uses SDL_SymToASCII() to get the keyname to use SDL_GetKeyName(), | |
| 480 and change code which uses it to get the ASCII value of a sym to | |
| 481 use the 'unicode' member of the event keysym. | |
| 482 | |
| 483 0.9.12: | |
| 484 There is partial support for 64-bit datatypes. I don't recommend | |
| 485 you use this if you have a choice, because 64-bit datatypes are not | |
| 486 supported on many platforms. On platforms for which it is supported, | |
| 487 the SDL_HAS_64BIT_TYPE C preprocessor define will be enabled, and | |
| 488 you can use the Uint64 and Sint64 datatypes. | |
| 489 | |
| 490 Added functions to SDL_endian.h to support 64-bit datatypes: | |
| 491 SDL_SwapLE64(), SDL_SwapBE64(), | |
| 492 SDL_ReadLE64(), SDL_ReadBE64(), SDL_WriteLE64(), SDL_WriteBE64() | |
| 493 | |
| 494 A new member "len_ratio" has been added to the SDL_AudioCVT structure, | |
| 495 and allows you to determine either the original buffer length or the | |
| 496 converted buffer length, given the other. | |
| 497 | |
| 498 A new function SDL_FreeWAV() has been added to the API to free data | |
| 499 allocated by SDL_LoadWAV_RW(). This is necessary under Win32 since | |
| 500 the gcc compiled DLL uses a different heap than VC++ compiled apps. | |
| 501 | |
| 502 SDL now has initial support for international keyboards using the | |
| 503 Latin character set. | |
| 504 If a particular mapping is desired, you can set the DEFAULT_KEYBOARD | |
| 505 compile-time variable, or you can set the environment variable | |
| 506 "SDL_KEYBOARD" to a string identifying the keyboard mapping you desire. | |
| 507 The valid values for these variables can be found in SDL_keyboard.c | |
| 508 | |
| 509 Full support for German and French keyboards under X11 is implemented. | |
| 510 | |
| 511 0.9.11: | |
| 512 The THREADED_EVENTS compile-time define has been replaced with the | |
| 513 SDL_INIT_EVENTTHREAD flag. If this flag is passed to SDL_Init(), | |
| 514 SDL will create a separate thread to perform input event handling. | |
| 515 If this flag is passed to SDL_Init(), and the OS doesn't support | |
| 516 event handling in a separate thread, SDL_Init() will fail. | |
| 517 Be sure to add calls to SDL_Delay() in your main thread to allow | |
| 518 the OS to schedule your event thread, or it may starve, leading | |
| 519 to slow event delivery and/or dropped events. | |
| 520 Currently MacOS and Win32 do not support this flag, while BeOS | |
| 521 and Linux do support it. I recommend that your application only | |
| 522 use this flag if absolutely necessary. | |
| 523 | |
| 524 The SDL thread function passed to SDL_CreateThread() now returns a | |
| 525 status. This status can be retrieved by passing a non-NULL pointer | |
| 526 as the 'status' argument to SDL_WaitThread(). | |
| 527 | |
| 528 The volume parameter to SDL_MixAudio() has been increased in range | |
| 529 from (0-8) to (0-128) | |
| 530 | |
| 531 SDL now has a data source abstraction which can encompass a file, | |
| 532 an area of memory, or any custom object you can envision. It uses | |
| 533 these abstractions, SDL_RWops, in the endian read/write functions, | |
| 534 and the built-in WAV and BMP file loaders. This means you can load | |
| 535 WAV chunks from memory mapped files, compressed archives, network | |
| 536 pipes, or anything else that has a data read abstraction. | |
| 537 | |
| 538 There are three built-in data source abstractions: | |
| 539 SDL_RWFromFile(), SDL_RWFromFP(), SDL_RWFromMem() | |
| 540 along with a generic data source allocation function: | |
| 541 SDL_AllocRW() | |
| 542 These data sources can be used like stdio file pointers with the | |
| 543 following convenience functions: | |
| 544 SDL_RWseek(), SDL_RWread(), SDL_RWwrite(), SDL_RWclose() | |
| 545 These functions are defined in the new header file "SDL_rwops.h" | |
| 546 | |
| 547 The endian swapping functions have been turned into macros for speed | |
| 548 and SDL_CalculateEndian() has been removed. SDL_endian.h now defines | |
| 549 SDL_BYTEORDER as either SDL_BIG_ENDIAN or SDL_LIL_ENDIAN depending on | |
| 550 the endianness of the host system. | |
| 551 | |
| 552 The endian read/write functions now take an SDL_RWops pointer | |
| 553 instead of a stdio FILE pointer, to support the new data source | |
| 554 abstraction. | |
| 555 | |
| 556 The SDL_*LoadWAV() functions have been replaced with a single | |
| 557 SDL_LoadWAV_RW() function that takes a SDL_RWops pointer as it's | |
| 558 first parameter, and a flag whether or not to automatically | |
| 559 free it as the second parameter. SDL_LoadWAV() is a macro for | |
| 560 backward compatibility and convenience: | |
| 561 SDL_LoadWAV_RW(SDL_RWFromFile("sample.wav", "rb"), 1, ...); | |
| 562 | |
| 563 The SDL_*LoadBMP()/SDL_*SaveBMP() functions have each been replaced | |
| 564 with a single function that takes a SDL_RWops pointer as it's | |
| 565 first parameter, and a flag whether or not to automatically | |
| 566 free it as the second parameter. SDL_LoadBMP() and SDL_SaveBMP() | |
| 567 are macros for backward compatibility and convenience: | |
| 568 SDL_LoadBMP_RW(SDL_RWFromFile("sample.bmp", "rb"), 1, ...); | |
| 569 SDL_SaveBMP_RW(SDL_RWFromFile("sample.bmp", "wb"), 1, ...); | |
| 570 Note that these functions use SDL_RWseek() extensively, and should | |
| 571 not be used on pipes or other non-seekable data sources. | |
| 572 | |
| 573 0.9.10: | |
| 574 The Linux SDL_SysWMInfo and SDL_SysWMMsg structures have been | |
| 575 extended to support multiple types of display drivers, as well as | |
| 576 safe access to the X11 display when THREADED_EVENTS is enabled. | |
| 577 The new structures are documented in the SDL_syswm.h header file. | |
| 578 | |
| 579 Thanks to John Elliott <jce@seasip.demon.co.uk>, the UK keyboard | |
| 580 should now work properly, as well as the "Windows" keys on US | |
| 581 keyboards. | |
| 582 | |
| 583 The Linux CD-ROM code now reads the CD-ROM devices from /etc/fstab | |
| 584 instead of trying to open each block device on the system. | |
| 585 The CD must be listed in /etc/fstab as using the iso9660 filesystem. | |
| 586 | |
| 587 On Linux, if you define THREADED_EVENTS at compile time, a separate | |
| 588 thread will be spawned to gather X events asynchronously from the | |
| 589 graphics updates. This hasn't been extensively tested, but it does | |
| 590 provide a means of handling keyboard and mouse input in a separate | |
| 591 thread from the graphics thread. (This is now enabled by default.) | |
| 592 | |
| 593 A special access function SDL_PeepEvents() allows you to manipulate | |
| 594 the event queue in a thread-safe manner, including peeking at events, | |
| 595 removing events of a specified type, and adding new events of arbitrary | |
| 596 type to the queue (use the new 'user' member of the SDL_Event type). | |
| 597 | |
| 598 If you use SDL_PeepEvents() to gather events, then the main graphics | |
| 599 thread needs to call SDL_PumpEvents() periodically to drive the event | |
| 600 loop and generate input events. This is not necessary if SDL has been | |
| 601 compiled with THREADED_EVENTS defined, but doesn't hurt. | |
| 602 | |
| 603 A new function SDL_ThreadID() returns the identifier associated with | |
| 604 the current thread. | |
| 605 | |
| 606 0.9.9: | |
| 607 The AUDIO_STEREO format flag has been replaced with a new 'channels' | |
| 608 member of the SDL_AudioSpec structure. The channels are 1 for mono | |
| 609 audio, and 2 for stereo audio. In the future more channels may be | |
| 610 supported for 3D surround sound. | |
| 611 | |
| 612 The SDL_MixAudio() function now takes an additional volume parameter, | |
| 613 which should be set to SDL_MIX_MAXVOLUME for compatibility with the | |
| 614 original function. | |
| 615 | |
| 616 The CD-ROM functions which take a 'cdrom' parameter can now be | |
| 617 passed NULL, and will act on the last successfully opened CD-ROM. | |
| 618 | |
| 619 0.9.8: | |
| 620 No changes, bugfixes only. | |
| 621 | |
| 622 0.9.7: | |
| 623 No changes, bugfixes only. | |
| 624 | |
| 625 0.9.6: | |
| 626 Added a fast rectangle fill function: SDL_FillRect() | |
| 627 | |
| 628 Addition of a useful function for getting info on the video hardware: | |
| 629 const SDL_VideoInfo *SDL_GetVideoInfo(void) | |
| 630 This function replaces SDL_GetDisplayFormat(). | |
| 631 | |
| 632 Initial support for double-buffering: | |
| 633 Use the SDL_DOUBLEBUF flag in SDL_SetVideoMode() | |
| 634 Update the screen with a new function: SDL_Flip() | |
| 635 | |
| 636 SDL_AllocSurface() takes two new flags: | |
| 637 SDL_SRCCOLORKEY means that the surface will be used for colorkey blits | |
| 638 and if the hardware supports hardware acceleration of colorkey blits | |
| 639 between two surfaces in video memory, to place the surface in video | |
| 640 memory if possible, otherwise it will be placed in system memory. | |
| 641 SDL_SRCALPHA means that the surface will be used for alpha blits and | |
| 642 if the hardware supports hardware acceleration of alpha blits between | |
| 643 two surfaces in video memory, to place the surface in video memory | |
| 644 if possible, otherwise it will be placed in system memory. | |
| 645 SDL_HWSURFACE now means that the surface will be created with the | |
| 646 same format as the display surface, since having surfaces in video | |
| 647 memory is only useful for fast blitting to the screen, and you can't | |
| 648 blit surfaces with different surface formats in video memory. | |
| 649 | |
| 650 0.9.5: | |
| 651 You can now pass a NULL mask to SDL_WM_SetIcon(), and it will assume | |
| 652 that the icon consists of the entire image. | |
| 653 | |
| 654 SDL_LowerBlit() is back -- but don't use it on the display surface. | |
| 655 It is exactly the same as SDL_MiddleBlit(), but doesn't check for | |
| 656 thread safety. | |
| 657 | |
| 658 Added SDL_FPLoadBMP(), SDL_FPSaveBMP(), SDL_FPLoadWAV(), which take | |
| 659 a FILE pointer instead of a file name. | |
| 660 | |
| 661 Added CD-ROM audio control API: | |
| 662 SDL_CDNumDrives() | |
| 663 SDL_CDName() | |
| 664 SDL_CDOpen() | |
| 665 SDL_CDStatus() | |
| 666 SDL_CDPlayTracks() | |
| 667 SDL_CDPlay() | |
| 668 SDL_CDPause() | |
| 669 SDL_CDResume() | |
| 670 SDL_CDStop() | |
| 671 SDL_CDEject() | |
| 672 SDL_CDClose() | |
| 673 | |
| 674 0.9.4: | |
| 675 No changes, bugfixes only. | |
| 676 | |
| 677 0.9.3: | |
| 678 Mouse motion event now includes relative motion information: | |
| 679 Sint16 event->motion.xrel, Sint16 event->motion.yrel | |
| 680 | |
| 681 X11 keyrepeat handling can be disabled by defining IGNORE_X_KEYREPEAT | |
| 682 (Add -DIGNORE_X_KEYREPEAT to CFLAGS line in obj/x11Makefile) | |
| 683 | |
| 684 0.9.2: | |
| 685 No changes, bugfixes only. | |
| 686 | |
| 687 0.9.1: | |
| 688 Removed SDL_MapSurface() and SDL_UnmapSurface() -- surfaces are now | |
| 689 automatically mapped on blit. | |
| 690 | |
| 691 0.8.0: | |
| 692 SDL stable release |
